The hood may be made of galvanized sheet metal and secured to the woodensection in any suitable way. It will be seen that the hood adds to thedurability of the post by preventing water from reaching the interior ofthe metal section b and increases its safety in rainy weather.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 25th day of May, A. D. 1896.
